Intake Manifold Gasket

January 11th, 2016 by

INTAKE MANIFOLD GASKET If your engine runs rough or overheats, a leaky intake manifold gasket may be the culprit. Location: The intake manifold is an aluminum or plastic cover attached to the top of the engine by an intake manifold gasket made of plastic and rubber. Purpose: It directs the air-fuel mixture in the engine to

Engine Oil

ENGINE OIL Don’t Neglect According to a recent survey of owners of vehicles that range in age from new to 15 years old, nearly four in ten of those polled indicated that they either never checked their engine oil or only have it checked when they take their automobiles in for service. In light of

Engine Mounts

Engine Mounts What they do: Engine mounts support the engine and transmission. Most are of simple design, with metal attachment plates and large rubber insulator blocks that dampen noise and vibration from being transmitted to the rest of the vehicle. Signs of problems: While engine mounts are seldom checked, thumping or rattling noises coming from

Fuel Injectors

  Maintaining Precision – Fuel Injectors Over the past three decades, as fuel injectors moved from the intake manifold to the combustion chamber, they have become more precise in dispensing fuel. To maintain this precision, vehicle owners should be on their guard for signs that their vehicles’ fuel injectors require service or replacement. Signs For

Air Filter

Air Filter Today’s Diesel Engines While today’s diesel engines are as durable as ever, changes in exhaust emissions technology make it especially important to observe air-filter replacement recommendations. In particular, turbo-charged diesel engines use high volumes of air to provide added power and help with emissions control. With this in mind, replacing and servicing the

Worn Piston Rings

Worn Piston Rings  The Signs When drivers notice excessive oil consumption, white or gray exhaust smoke, poor acceleration, and/or overall loss of power or poor engine performance, they may be seeing signs of worn piston rings. These hoop-shaped pieces of metal fit around the circumference of each piston, providing a seal between the piston and the

Leaky Manifold Gasket

August 3rd, 2015 by

A LEAKY MANIFOLD GASKET The exhaust manifold gasket forms a seal where the surfaces of the exhaust manifold and the cylinder head meet. As the metal surfaces on each side of the gasket expand and contract (due to the high temperatures of burned exhaust gases exiting from the engine’s cylinder), the gasket may develop leaks.

Harmonic Balancer

June 2nd, 2015 by

PRESERVING HARMONIC BALANCE   When mention is made of a “harmonic balancer” some may think it has to do more with the metaphysical properties of healing crystals than a car engine. The fact is, however, that a harmonic balancer is a circular device composed of rubber and metal that is bolted at the front end

Reducing Emissions

May 20th, 2015 by

Reducing Emissions (EGR) System: Purpose The exhaust-gas-recirculation (EGR) system reduces harmful NOx emissions that contribute to air pollutions by recirculating exhaust gas back through the intake manifold into the engine. There, it acts as a cooling agent to lower combustion temperatures. All this is done with the intention of preventing mono-nitrogen oxides (NO and NO2)

Engine Idle (Speculation)

April 22nd, 2015 by

   ENGINE IDLE (Speculation) When an engine will not idle or run correctly, a vacuum leak may be the culprit. Such leaks allow: Unmetered air to enter the engine  Upset the air/fuel ratio leading to a disruption in the operation of the computer system and a wide range of symptoms. An air leak should be
